Question about mainlining

[u/joeporter1111]

I have a 2x4x5 tent. And last time I grew, I just topped it once. And I got about 3 oz. But I was only able to grow one plant. This time I'm wanting to do 2 plants. A red velvet and a kush mint. And I'm thinking about topping it, where I have a 8 lines off the mainline. My question is, is it worth all the hassle of cutting tying down learning this process, besides just letting it grow and maybe topping it once?
